MEANS FOR LA-UNCHlNG LIFE-BOATS FROM VESSE'LS.

SPECIFICATION forming part of Letters Patent No. 634,028, dated October 3, 1899.

Application filed October 27, 1898. Serial No. 694,677. (No model.)

To all whmn it may concern Be it known that we, JAMES POLLITZ, a subect of the Emperor of Germany,) but having declared my intention of becoming a citizen,

of the United States and taken my first papers for such purpose,) and EDWARD HY. 00X,-

a subject of the Queen of England, both residing in the borough of Manhattan, city of New York, county and State of New York,

have invented certain new and useful Im tion and launching them in the water at a sufficient distance from'the vessel on which they are carried as to be more free than heretofore fgom the motion or wash of the sea against the s 1p.

To this end the intention consists in providing suitable supporting-davits, which are hinged or pivotally attached to the side of the vessel a short distance above the water-line, said davit-s being adapted to swing a life-boat outwardly and launch the same away from thevessel the distance of their length and to turn the boat at an angle to the side of the vessel, as hereinafter more fully described, and pointed out in the claim.

In the drawings, Figure l is a perspective view of a portion of a vessel, showing'a lifeboat on one side thereof in position on the deck and another lowered into the water on the opposite side, but connected with the davits by which it is supported and launched. Fig. .2 is a plan view of the same, showing by dotted lines the position of the life-boat when at rest and secured on the deck and by full lines its position when lowered into the water. Fig. 3 is a side view of a portion ot a vessel with the davits in an upright position and the life-boat at rest and secured over the deck, while Figs. 4. and 5 are details of blocks or castings attached to the side of the vessel and provided-with lugs having apertures for receiving a pin or bolt by which the forked end of the davit maybe hinged or pivotally secured to the same; Fig. 6 shows'the lower forked end of one of the'davits.

, In the drawings, A represents a vessel; a a, thesupports for a life-boat B when at rest above thedeok,.and to which it is secured in the usual manner by wedges or keys I) b. The life-boat is connected by suitable tackle c c to the upper end of the clavits O O, which also connect by suitable tackle with the guys cl d for raising and lowering the same. The davit"sC C are preferably provided with forked ends e, which are hinged or pivoted to the lugsfon the castings D, secured to the side of the vessel at a point not far from the wa terlinesay three or four feet above the same. The davits O C extend upward along the side of the vessel and far enough above the edge of the same to support a life-boat in.

the usual place and position, and the means by which it is secured need notvvary from those ordinarily in use forsuch purposes; but

the davits need not have the usualcurve at the 7 top, as the life-boat may be swung inwardly over the deck by the tackle a c, as shown in Fig. l.

W'e form the hinge or pivotal connection for the lower end of one of the davits so that it will swing outwardly at a different angle to the side of the vessel from the other one, and thereby give the bow of the life-boat an out.- ward turn during its lowering and launching. This movementwill greatly facilitate the rowing at the outset and occasion less delay than that which ordinarily occurs when the lifeboat is lowered parallel to the vessel and receives the wash broadside which makes difficulty in starting the rowing.

As the means by which the lowering and davits, those who are in it will be subjected to less danger of loss by the movements of the vessel or of the water than when'launched in the usual way.

Another advantage of this means for supportiu g and launching such boats is that they can be lowered from either side of thevessel,

which has not heretofore been usual nor always possible, owing to the fact that fre- 10 cause one of them to swing outwardly at a different angle to the side oi the vessel from that of the other, in combination with means for connecting a 1ife-boat to the free ends of said davits, and for manipulating the same while bein g lowered,substantially as set forth.
